At first I was sympathetic toward option 1, but then I realized that with ES6 modules all script loading becomes async, so it would be literally impossible to use custom elements in a .html file (unless your strategy was to wait for element registration, XHR the .html file into a string, then do `document.documentElement.innerHTML = theBigString`).

In other words, in an ES6 modules world, all custom elements are upgraded elements.
